Arquebusiers can only stand two deep, archers are effective even six deep, when the rear ranks shoot with a high trajectory. 火绳枪兵只能站两列,而长弓兵则更有效率因为他能有六列的纵深,只要后面的人使用抛射。
The combined trajectory is adopted by supersonic anti-ship missile, cruising at high altitude and flying over the sea at low altitude. The great height difference between high trajectory and low one makes the design of down-slide trajectory become difficult. 采用高空巡航和低空掠海飞行弹道相结合的超音速反舰导弹,由于其高低空弹道高度相差甚大,因而下滑段的弹道设计是一个难题。
It requires athletes in as horizontal speed using surplus under the premise of vertical velocity, try to improve, to obtain a high trajectory far vacated. 它要求运动员在尽可能利用剩余水平速度的前提下,尽量提高垂直速度,以获得一个较高较远的腾空轨迹。
In recent years, anti-personnel grenade has achieved air fixed blast function which not only can use low-ballistic stretching, but also can be a high trajectory angle in the fight against the realization of the goal over. 近年来,杀伤榴弹已实现了空中定点爆炸功能,既可采用低伸弹道,也可采用高射角弹道在目标上空实现打击。
The other is quicker, but its accuracy is unsatisfied because the simplified model of high precision trajectory is used. 一类速度很快,但因为使用的是简化模型,因而精度较差,难以满足未来高精度测控的需要。
